How to Make Low Carb Philly Cheesesteak Casserole

Ingredients

2 lbs ground beef (80/20 fat ratio preferred)
1 large onion (diced)
2 large bell peppers (green, red, or mixed, diced)
2 cloves garlic (minced)
8 oz cream cheese (softened to room temperature)
2 tbsp Worcestershire sauce
Salt and pepper (to taste)
8 oz provolone cheese (sliced)
1.5 cups mozzarella cheese (shredded)
1 tbsp olive oil

Step-by-Step Instructions

Preheat your oven to 350°F (175°C) and spray a 9×13 baking dish with non-stick spray. This will help prevent the casserole from sticking as it cooks and makes cleanup easier.
In a large skillet, heat olive oil over medium heat. Once it’s hot, add the diced onions and bell peppers. Sauté these ingredients for about 5-6 minutes until they start to soften and become fragrant, releasing their wonderful aroma.
Stir in the minced garlic and cook for another 30 seconds, making sure to stir constantly to avoid burning. The rich flavors of garlic will elevate the dish significantly.
Add the ground beef to the skillet, breaking it up with a spatula. Season generously with salt and pepper, cooking for 7-8 minutes until the meat is browned and no pink remains. Drain any excess fat if needed for a leaner casserole.
Stir in the Worcestershire sauce, which adds a depth of flavor to the meat mixture. Lower the heat and mix in the softened cream cheese until fully melted and creamy, creating a luscious sauce.
Transfer the beef mixture to your prepared baking dish and spread it evenly. Layer torn pieces of provolone cheese over the top and finish with shredded mozzarella. The combination of these cheeses gives a delightful cheesy pull when serving.
Bake in the preheated oven for 22-25 minutes, or until the cheese is melted, bubbly, and slightly golden on top. Let it rest for about 5 minutes before serving to allow the flavors to meld together.

Pro Tips

Quality of Beef Matters: Choosing a ground beef with higher fat content, like an 80/20 ratio, ensures the dish remains juicy and flavorful. Leaner beef may dry out and not offer the same richness.
Don’t Rush the Veggies: Sautéing the onions and peppers is essential for unlocking their flavors. Take your time with this step, as it adds a delicious sweetness to the dish.
Cream Cheese Temperature: Ensure the cream cheese is softened to room temperature before adding it to the skillet. This helps it blend smoothly and creates a creamy sauce without clumps.
Watch the Baking Time: Keep an eye on the casserole as it bakes. Ovens can vary, and you want that golden, bubbly cheese without overcooking.
Customize with Spices: Add a dash of paprika or cayenne for a mild kick! These spices can elevate the overall taste and give it a personalized touch.
Leftover Options: This casserole is perfect for leftovers! Reheating in an oven or skillet can help retain the original texture and flavor better than a microwave.

How to Store Low Carb Philly Cheesesteak Casserole

For storage, allow the casserole to cool completely before transferring it to an airtight container. It can be kept in the refrigerator for about 3-4 days.

To reheat, simply thaw it in the fridge overnight before warming it up. Alternatively, you can reheat it straight from frozen, though it may take a bit longer.

Tips to Make Low Carb Philly Cheesesteak Casserole

Season Correctly: Taste as you go! Seasoning is key to ensuring that each ingredient shines. Don’t skip on the salt and pepper.
Experiment with Cheese: Try different cheese combinations for a different experience. Cheddar, Swiss, or even a blend can bring new flavors to the table.
Chop Veggies Smaller: For more uniform bites, chop the peppers and onions into smaller pieces. It makes for an overall better texture in the casserole.
Adjust Cooking Times for Texture: Some people prefer the veggies crunchier. So feel free to adjust how long you sauté them based on your personal preference.

Variations

Spicy: Add jalapeños or diced green chilies for a spicy kick!
Vegan: Substitute ground beef with lentils or meat substitutes, using vegan cream cheese and cheese alternatives.
Gluten-free: This recipe is already gluten-free, but double-check the labels on Worcestershire sauce or any cheese you may use.

Storage and Reheating

To keep your leftovers fresh, store them in an airtight container in the fridge. For reheating, you can use a microwave, oven, or skillet.

Microwave: Place a portion in a microwave-safe dish and heat for 1-2 minutes, stirring halfway through.
Oven: Preheat the oven to 350°F, then cover the casserole with foil and heat for about 15-20 minutes.
Skillet: Heat with a little bit of oil or butter in a skillet over medium heat, stirring periodically until warmed through.

Customization Ideas

Feel free to adjust flavors based on your preferences! Adding different spices, such as cumin or Italian seasoning, can transform the flavor profile. Top with crunchy fried onions or fresh herbs just before serving for added texture and visual appeal.

Common Mistakes to Avoid

Crowding the Pan: To properly sauté the vegetables, don’t overcrowd the skillet. This can lead to steaming instead of browning.
Undercooking Beef: Make sure the beef is browned completely. Undercooked beef can spoil the texture and flavor of the dish.
Using Cold Cream Cheese: Failing to soften the cream cheese can lead to a lumpy sauce. Always let it come to room temp first.
Skipping the Resting Period: Allow the casserole to sit for a few minutes after baking. This helps to settle the flavors and makes serving easier.
Overbaking: Keep track of your baking time! Overbaking can cause the cheese to harden instead of remaining gooey.

Serving Occasions
